A relation between two or more persons, by which one party, usually called the agent or attorney, is authorized to do certain acts for, or in relation to the rights or property of, the other, who is denominated the principal, constituent, or employer. Prof. Joel Parker, MS. Lect. 1851. A contract by which one person, with greater or less discretionary power, under- takes to represent another in certain busi- ness relations. Whart. Ag. 1. The right on the part of the agent to act, is termed his authority or power. In some instances the au- thority or power must be exercised in the name of the principal, and the act done is for his benefit alone: In others, it may be executed in the name of the agent, and if the power is coupled with an in- terest on the part of the agent, it may be executed for his own benefit; Prof. Joel Parker, Harvard Law School Lect. 1851. The creation of the agency, when express, may be either by deed, in writing not by deed, or by a verbal delegation of authority; 2 Kent 612; 9 Ves. 250; 11 Mass. 27, 97, 288; 1 Binn. 450; 4 Johns. Ch. 667. When the agency is not express, it may be inferred from the relation of the parties and the nature of the employment, without proof of any express appointment; 2 Kent 613; 15 East 400; 1 Wash. Va. 19: 5 Day 556. Where relations exist which will con- stitute agency, it will be such whether the parties understand it to be or not; 72 Tex. 115. The admissions of a supposed agent cannot prove the existence of the agency: 23 III. App. 116; 48 id. 659; 35 Kan. 391; 70 Hun 568; 51 Minn. 141; 116 Mo. 51. In most of the ordinary transactions of business the agency is either conferred verbally, or is implied from circumstances. But where the act is required to be done in the name of the principal by deed. the au- thority to the agent must also be by deed, unless the principal be present and verbally or impliedly authorize the agent to fix his name to the deed; 1 Liverm. Ag. 35: Paley,. Ag. 157; Story, Ag. SS 49.51; 5 Binn. 613; 1 Wend. 424; 9 id. 54, 68; 12 id. 525; 14 S. & R. 331. The authority may be general, when it extends to all acts connected with a partic- ular business or employment; or special, when it is confined to a single act; Story, Ag. § 17; Mech. Ag. 284, 285;21 Wend. 279 ; 9 Ν. Η. 263; 3 Blackf. 436; 82 Cal. 1. If the powers are special, they form the limits of the authority; if general, they will be more liberally construed, according to the necessities of the occasion and the course of the transaction. The agency must be antecedently given, or subsequently adopted; and in the latter case there must be an act of recognition, or an acquiescence in the act of the agent from which a recognition may be fairly implied; 2 Kent 614. If, with full knowledge of what the agent has done, the principal/ ratify the act, the ratification will be equiv- alent to an original authority,-according to the maxim, omnis ratihabitio retrotra- hitur et mandato æquiparatur; Paley, Ag. 172; 4 Ex. 798. The ratification relates back to the original making of the contract; 31 L. J. Ex. 163; 57 Fed. Rep. 973; except as to intermediate vested rights; 4 Ct. Cl. 511; 49 Ill. 59; 43 Mo. 113; 12 Minn. 255. It must be ratified in its entirety; 31 N. Y. 611; 1 Oreg. 115; 45 Ga. 153; 27 Mo. 163; 31 Iowa 547; 24 Neb. 653; 15 So. Rep. (La.) 16; and subject to the charges imposed by the agent; 9 H. L. C. 391. If the prin- cipal accepts the benefit of a contract, he is responsible for the fraudulent represent- ations of the agent, although made without authority; 85 Tenn. 139; 40 Minn. 476; 78 Cal. 490; 157 Mass. 248; 65 Hun 182; 144 Pa. 398. An intention to ratify may be presumed from the silence of the principal who has received a letter from the agent informing him of what has been done on his account; 12 Wall. 358; 2 Biss. 255; 105 Mass. 551; 49 Pa. 457; 69 id. 426; 21 Mich. 374; 37 111. 442; 26 Iowa 38; 27 Tex. 120; 13 Colo. 69; or from any acts inconsist- ent with a contrary presumption; .26 Me. 84; 69 Pa. 426; 59 Ill. 23; 12 Kan. 185; or from a suit by the principal; 56 Me. 564 ; 21 Ark. 539; 28 III. 135; 9 B & C. 59; 12 Wall. 681; 12 Johns. 300; 8 Cow. N. Y. 281; 4 Wash. C. C. 549; 14 S. & R. 30; or by adoption of a submission to arbitration, although the agent exceeded his authority; 57 Conn. 105; or by keeping and enforcing a mortgage, obtained by an agent for the release of another mortgage; 63 Mich. 599. Ratification can only take place where the agent professed to act for the person rati- fying; 5 B. & C. 909; Leake, Cont. 470. Thus a forged signature to a note cannot be ratified; L. R. 6 Ex. 89; contra, 46 Me. 176; 32 III. 387; 33 Conn. 95; 42 Pa. 143; Whart. Ag. § 71. A principal cannot ratify the acts of his agent where he has no knowledge of such acts; 71 Md. 200; 76 Ia. 129. The acts of the agent must be disap- proved within a reasonable time after notice, or the principal will be considered as having ratified them by his silence; 45 La. Ann. 847. The business of th
